CORKING APPARATUS.

SPECIFICATION forming part of Letters Patent No. 726,621, dated April28, 1903. Application filed June 7, 1902. Serial No. 110,597. (Nomodel.)

vented certain new and useful Improvements,

in Oorking Apparatus, of which the following is a specification.

The present invention relates to an apparatus for the corking ofpasteurizing vessels with the exclusion of air, which is especiallyadaptable to pasteurizing of beer in large transport vessels.

This apparatus comprises an overflow-chamber screwed on the cork-supportand fitted I 5 with a corking-machine provided with a sleeve or case tohold the cork and furnished with grooves. The object of these grooves isto allow of the passage of the liquid from the vessel to the chamber orin the opposite di- 2o rection during the pasteurization after placingthe cork in position, and the cork may then be forcedinto the bung-holewith the desired exclusion of air.

In the accompanying drawings, Figures 1 2 5 and 2 show in section thecorking apparatus when the vessel is open and closed, respectively; andFig. 3 shows in side elevation the sleeve or case provided with grooves.

As can be seen from the drawings, the ap- 0 paratus comprises a chamber20, capable of being temporarily secured to the cork-holder 40,containing the bung-hole, said cork-holder being permanently fixed tothe wall of the vessel containing the liquid. The said cham- 5 ber issecured to the cork-holder by means of the clamping-screw 50, whichengages excluding air therefrom, the combination of a chamber, a tubularneck leading therefrom, a cork-holding coupling in the wall of thevessel containing the liquid, a movable sleeve the tubular neck 21. Inthis tubular neck is a sleeve 52 for holding the cork, and it isprovided on its outside with longitudinal o grooves, while inside itreceives the enlarged lower end of a Vertically-movable plunger orpiston 45. The sleeve52, in which the cork i1 is placed, will sometimesbe in the'upper extended part of the support and'sometimes 5 in thelower tubular portion 21 of the chamber 20, so that after screwing theclampingscrew 50 onto the support the passages between the bung-hole andthe interior of the chamber 20 will be established by means of If nowthe liquid to be corked up is heated for pasteurizing, it passes, bymeans of the passages 51, into the chamber -20 during its increase involume, while during the cooling of the pasteurized liquid the latter bythe same channel again flows back into the pasteurizing apparatus. Toclose the vessel, pressure is applied, by means of the plunger 45, t0the cork 41', placed in the sleeve 52, and the cork is forced into thebung-hole, as shown in Fig. 2, sothat the pasteurizing-chamber is closedwith the desired exclusion of air, after which the clamping-screw may beunscrewed from the support 40 of the chamber 20, and

the corkingmachine arranged therein may be taken apart from the support.

What I claim, and desire to secure by Letters Patent of the UnitedStates, is

1. In an apparatus for corking vessels while excluding air therefrom,the combination of a chamber to receive the surplus liquid, with aplunger passing therethrough to force the cork into its hole, a tubularconnection between said chamber and the bung-hole, a sleeve in saidtubular connection to hold the cork arid provided with grooves on itsexterior forming passages from the vessel to be scribed.

2. In an apparatus for corking vessels while excluding air therefrom,the combination of a chamber, a plunger to force the cork into its hole,a sleeve to hold said cork and provided with grooves and a tubularsupport holding said sleeve and supporting said chamber, substantiallyas described.

3. In an apparatus for corking vessels While having externallongitudinal grooves and located in said tubular neck, a plunger workingthrough said sleeve, and a clampingscrew for securing the'neck to thecork-hold- .ing coupling, substantially as described.

In testimony whereof I have hereunto set my hand in the presence of twowitnesses.
